* Role, ClusterRole and their bindings for cloud-provider is put under system namespace. Their addonmanager mode switches to EnsureExists. ([#67224](https://github.com/kubernetes/kubernetes/pull/67224), [@grayluck](https://github.com/grayluck))

`Interrupted()` instead. If you are returning `ErrWaitTimeout` from your own methods, switch to creating a location specific `cause err` and pass it to the new method `wait.ErrorInterrupted(cause) error` which will ensure `Interrupted()` returns true for your loop. 
  
  The `wait.NewExponentialBackoffManager` and `wait.NewJitteringBackoffManager` functions have been marked as deprecated.  Callers should switch to using the `Backoff{...}.DelayWithReset(clock, resetInterval)` method and must...

* Switch default etcd version to 3.0.14. ([#36229](https://github.com/kubernetes/kubernetes/pull/36229), [@wojtek-t](https://github.com/wojtek-t))
    * Switch default storage backend flag in apiserver to `etcd3` mode.

- Fix the bug that EndpointSlice for masters wasn't created after enabling EndpointSlice feature on a pre-existing cluster. ([#84421](https://github.com/kubernetes/kubernetes/pull/84421), [@tnqn](https://github.com/tnqn))
- Switched intstr.Type to sized integer to follow API guidelines and improve compatibility with proto libraries ([#83956](https://github.com/kubernetes/kubernetes/pull/83956), [@liggitt](https://github.com/liggitt))

* Role, ClusterRole and their bindings for cloud-provider is put under system namespace. Their addonmanager mode switches to EnsureExists. ([#67224](https://github.com/kubernetes/kubernetes/pull/67224), [@grayluck](https://github.com/grayluck))

- Kubeadm: Switched kubeadm to start using the CRI client library instead of shelling out of the `crictl` binary
  for actions against a CRI endpoint. The kubeadm deb/rpm packages will continue to install the `cri-tools`

  - build: Use go-runner:buster-v2.0.1 (built using go1.15.1)
  - bazel: Replace --features with Starlark build settings flag
  - hack/lib/util.sh: some bash cleanups
    
    - switched one spot to use kube::logging
    - make kube::util::find-binary return an error when it doesn't find
      anything so that hack scripts fail fast instead of with "binary not
      found errors".

    * A `ready` plugin has been included to report pod readiness
    * The `proxy` plugin has been deprecated. The `forward` plugin is to be used instead.
    * CoreDNS fixes the logging now that kubernetes’ client lib switched to klog from glog.
